Letters Patent No.'102,282, dated April 26, 1870.

METALLIC PACKING FOR STATIONARY JOINTS.

The Schedule referred to in these Letters Patent and making part of thesame.

' To all whom 'it may concern Be it known that I, HARVEY T. LEE, ofMarysville, county of Yuba, State of California, have invented anImproved Metallic Packing for Stationary Joints and `a patent which wasgranted to Hall and Lee for an invention of the same character on the8th day of June, 1869, in which they claimed upsetting or thickening theopposite edges of plates of malleable metal, so as to form wedge-shapededges, upon which the corners of the joint to be packed were placed.

My present invention consists informing a metal packing for stationaryjoints out of any malleable wirc or other thin strips, rods, or bars ofsuch metal, and, by giving it a peculiar shape, make it answer the samepurpose as that covered by the patent above mentioned, and that at aless cost in its manufacture and production.

In order to more fully'illustrate and explain my invention, reference ishad to the accompanying drawings forminga part of this specification, inwhich(- A represents a steam-chester other surface, upon which a coveris to be fitted so as to give a steam or water-tight joint.

'lo render this and other similar joints steam or water-tight, I take asuitable-sized wire, rod, bar, or strip of copper or other malleablemetal, and give to it an oval or other shape which will produce two thinsharp edges upon opposite sides. 4

The sharp-edged wire thus formed I bend to the desired shape to fitaround and upon the outer edge of the surface to be packed, in a mannersimilar to the oval wire, marked B, uniting the two ends with solder orother brazing material.

A second encircling band is then formed of the same material, and inthesame manner, to lit around the .inner edgev of the surfacefas shownby the wire marked O.

In order to protect the bolts D and prevent the steam fromescapingbeside a loosely-fitting one, I form rings, E, of the samematerial, which are then placed in the proper position between the outerand l inner bands G and D, for encircling the bolts and secure them tothe bands O and D by brazing or soldering, as above described. Theserings serve to unite the packing-frame, and thus prevent their becomingdisplaced.

l After this packing-frame has been properly placed upon the surface ofthe steam-chest, the cover is placed down upon` the frame, when, byturning the nuts rmly and strongly down upon the cover, the thin edgesof the wires will he compressed, or rather'upset, so asft'o t closely toboth surfaces, filling any depressions or une'venness in either of theparts, and thus furnishing a perfectly steam and water-tight joint.

A packing ma'de in this manner can be fitted upon surfaces of varioussizes, and, consequently, can be manufactured and put upon sale;Whereas, all the usual and ordinary forms have to be manufacturedexpressly for and fitted to the particular surface upon which it is tobe applied, unless two surfaces should be synony- Having thus describedmy invention, What I claim, and desire to secure by Letters Patent, is

A packing for stationary joints made out of malleable metallic strips,wires, or rods, by forming upon them two opposite sharp edges,substantially as above j
